Breeding with two shiny pokemon?

Accepted Answer

If you breed two Pokemon you caught/bred yourself, than the chance of hatching a shiny is still 1/8192(0.012%). No matter what, even both parents are shiny. However, there is a chance to increase the chance of getting a shiny. Pokemon from different countries breed the odds of a shiny are increased. using Onix for example:

if you breed a German Onix and a Onix you just caught (assuming you're not also playing with a German game version), the odds of hatching a shiny Pokemon are increased six times to about 1/1366 (or, in any of the 4th Generation games, the odds are increased four-fold to 1/2048)
